HP 58516A
GPS L1 DISTRIBUTION AMPLIFIER
1. INTRODUCTION
1.1. The HP 58516A GPS L1 Distribution
Amplifier is one component of a complete line of
GPS accessories for your GPS antenna system
available from Hewlett-Packard. These
accessories are designed to deliver precise
GPS signals over a wide temperature range and
in harsh environmental conditions.
1.2. The distribution amplifier is required if you
wish to distribute the signal from a single
antenna to as many as four GPS receivers.
2. DESCRIPTION
2.1.
The HP 58516A consists of a broadband,
unity gain amplifier and a 1:4 signal splitter.
Designed for use with GPS antennas, the unit
features a high degree of isolation to eliminate
feedback and interaction between any GPS
systems connected to it.
2.2. Power to the splitter is supplied by the
GPS timing receiver connected to Port 1.
3. USE WITH HP AND NON-HP SYSTEMS
3.1. Although designed for use with HP GPS
frequency and time receivers, the HP 58516A
can be used with other GPS receiver and
antenna systems.
3.2.
The HP
58516A operates over a voltage
range of +4.5 Vdc to +30
Vdc. Voltage is
supplied via the connecting cable (the center
conductor is positive with respect to the shield)
to Port 1 of a standard unit, or through an
external dc power input on a unit with Option
05Q.
Caution:
Power to the HP 58516A will be
passed to the rest of the antenna system. For
example, if a +30 Vdc supply is used to
power the HP 58516A, the +30 Vdc will be
passed through to the antenna. When using
the HP 58516A with an HP 58504A GPS
antenna, the maximum voltage should be no
greater than +5.5 Vdc.
